You can also insert a ping to localhost. This will take 4 seconds to complete (by default). It is considered a kludge by some, but works quite well all the same.
The command:
ping 127.0.0.1

I have used three LSI devices in my life. One plain SCSI (for a tape changer), a 3ware (now LSI) RAID card where the BBU went bad and the card died a few eeks later, and the replacement card
All I know mine got hotter than expected. And then the 1/2 year old BBU started complaining about imminent failure, not charging. A mont later the card failed
@Basil Exactly. And it's easier to buy an OEM server that isn't going to break than to train 3 padawans to do manual failovers because I'm already busy fixing something that just bumped up to the top of the priority list.

@ewwhite Nice redaction :) Seriously though… looks good to me. Maybe it's a marginal drive that's on it's way to failing and taking a long time to do IO?
Do you ever slap yourself in the forehead and say "Holy fuck! I don't know if I work for a startup!" If so, perform the following simple test. Does anyone wear a hoodie to work without getting fired? If so, you run the serious risk of being in the employ of a startup.
@Zoredache They're big into doing systems administration and development right.
Some people have misinterpreted doing their damn jobs like a rational human being as something called "devops."
I agree with much of the methodology, but the term grates on me.
So, who wants to be the one to ask a snarky question as an example of what the DevOps site would have on it? Like "How is this any different than ServeRFault?"
@WesleyDavid And many other people have decided that modern tools mean a development team can work without an operations team. These are the ones we hate
@Zypher At $NEWJOB, DevOps is a separate team that sits between dev and ops. Meaning, there's an entire development team, a dev-operations team, and a production-operations team
@JoelESalas Meta, man. Meta. And isn't that the total opposite of what devops means? Kinda like a peace rally where participants overturn cars and set them on fire? I mean... kinda like Canada?
@Basil Well, I dunno about that.... he did try to bind an interface to 0.0.0.0:80, so there may be no helping him, but at least we'd have people around who could identify the problem accurately.
Excuse me for a bit while I get a little sentimental. Tomorrow (the 27th of September) marks my two year anniversary with Stack Exchange – it was still called Stack Overflow Internet Services when I joined! I realized this about two or three weeks ago when I was setting up my trip to Denver for [...]
